Is it true that Miranda warnings are necessary only if the detainee knows they are being interrogated by a government agent?

Miranda warnings are not contingent upon the detainee's knowledge that they are being interrogated by a government agent. These warnings are required whenever a suspect is both in custody and subject to interrogation by law enforcement. The key aspect is the custody status and the intent of law enforcement to elicit information regarding the suspect's involvement in criminal activity.

The purpose of the Miranda warnings is to inform individuals of their rights to remain silent and to have an attorney present, ensuring that any statements made during interrogation are voluntary and informed. This legal requirement stems from the need to prevent coercive interrogations and protect the Fifth Amendment right against self-incrimination.

The correct understanding is that Miranda warnings are essential whenever someone is subjected to custodial interrogation, regardless of whether they understand the nature of their interaction with law enforcement or who is questioning them. Therefore, the assertion that these warnings are only necessary if the detainee realizes they are being interrogated by a government agent is inaccurate.
